A display system (10) for digital color images using six color light sources (12) or two or more multicolor LED arrays (212, 213) or OLEDs (220, 222) to provide an expanded color gamut. Apparatus (10) uses two or more spatial light modulators (20, 21), which may be cycled between two or more color light sources (12) or LED arrays (212, 213) to provide a six-color display output. Pairing of modulated colors using relative luminance helps to minimize flicker effects.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A method for displaying a color image from digital data comprising: (a) providing image data for at least a first and a second color to a first polymer light emitting diode and emitting said at least said first and said second color from said first polymer light emitting diode as a first multicolor modulated beam; (b) providing image data for at least a third and a fourth color to a second polymer light emitting diode and emitting said at least said third and said fourth color from said second polymer light emitting diode as a second multicolor modulated beam; (c) combining said first and said second multicolor modulated beams to form a combined multicolor modulated beam; and (d) directing said combined multicolor modulated beam to a display surface.
